WATER-CLOSET BOWL.

SPECIFICATION forming part of Letters Patent No. 771,068, dated September 27, 1904.

Application filed February 13, 1904. Serial No. 193,401. (No model-Y To all whom, it may concern:

Beitknown that we, MICHAEL D. HELFRICH and FORREST W. KINGSBURY, citizens of the United States, residing at Evansville, in the county of Vanderburg and State of Indiana, have invented certain new and useful Improvements in VVater-Closet Bowls, of which the following is a specification.

This invention is an improvement in watercloset bowls, having for an object, among others, to provide a novel construction for providing for washing down the closet without or with siphonic action, to do away with all splashing and agitation of the contents of the bowl, to avoid the noise incident to the operation of flushing the ordinary closet, and to provide for flushing from the rim after the contents of the bowl or trap-seal have been discharged; and the invention consists in certain novel constructions and combinations of parts, as will be hereinafter described and claimed.

In the drawings, Figure 1 is a perspective view of a closet-bowl embodying our invention. Fig. 2 is a vertical longitudinal section of the bowl; and Fig. 3 is a detail section illustrating the back supply instead of the top supply, as shown' in Fig. 2.

In the construction shown the bowl A has a trap-seal B, a supply pipe or passage C, leading from the top of the bowl to the trapseal B, a hollow rim D, having outwardly-inclined openings (Z and an inclined passage E, leading from the main supply-passage O to the hollow rim D and inclining upwardly from the passage or pipe C to the rim, as shown in Figs. 2 and 3. The outlet B from the trapseal B to the outlet-pipe F, leading to the sewer, is formed between the spoons Z) and b, and this passage or outlet B is of uniform area throughout, so the discharge of water therefrom will not be retarded or accelerated, so there will be no siphonic action at the discharge of the seal B nor will the passage of the contents of the trap-seal be choked in any Way at such point.

As best shown in Figs. 2 and 3, the main supply-passage C is of a uniform cross-sectional area from its upper end to the water level or line B of the trap-seal B, and from such point to the discharge of the said passage into the trap-seal the passage C gradually diminishes in area. In other words, the passage C does not diminish in cross-sectional area to the water-line of the trap-seal and gradually diminishes in area from said water-line to its communication with the trap-seal. This is an important feature of our invention, especially in connection with the inclined passage E, leading to the rim, as in operation the full force of the water supplied to the upper end of the pipe or passage 0 acts directly upon the surface of the water and washes out the bowl at the first flow of the water and before any water passes through the rim. The gradual reduction or contraction of the passage C below the waterline causes the water supply to back up through the passage E into the rim after the contents of the bowl have been discharged through the opening B. This avoids any splashing within the bowl, as the reason the ordinary closets now on the market splash is that the greatest amount of the water goes through the rim with such force as to compel it to splash when entering the bowl and striking the contents thereof, while we make the main supply-passage C of full size or area to the water-line of the trap-seal in order to prevent this splashing, the inclined passage E conveying water to the rim after the initial pressure has struck the body of water in-the lower end of the passage 0 and washed the deposit into the sewer, the main supply-pipe filling up and furnishing the rim with water to cleanse the sides of the bowl while the closet is still washing down. In the use of our construction it is utterly impossible for any water to pass to the rim until the initial flow of water has washed the deposit out of the trapseala The closet, as shown, is noiseless, because the action all takes place beneath the water-seal and deposits in the trap-seal, forming an undercurrent to the outlet, which noiselessly removes all deposits.

In Fig. 2 the bowl is shown adapted for a top supply, while in Fig. 3 a back supply is provided at G.

It will be noticed that the passages C and E contain sufficient water to reseal the trap after operation, as the main supply-pipe is of full size and unobstructed to the level of the water in the trap-seal, thus giving ample capacity to reseal the trap absolutely through the bottom outlet of the supply-pipe and not down through the bowl.

Actual practical tests enable us to state positively that a closet constructed by our invention, as shown, is noiseless and free from any splashing action.

By our invention we are able to make a closet-bowl somewhat similar to what are known as siphonic-action bowls; but our device being of the wash-down kind can be made much cheaper, usually at about threefourths the cost of the siphon-bowls, because of the simplicity of the construction, and only requires about one-half of the water which is necessary in the use of the bowls operating by siphonic action.

The passage E is relatively much smaller than the passage C, as we do not desire to susply much water to the rim. The angle of this passage E may be varied.

Having thus described our invention, what I we claim, and desire to secure by Letters Patent, is

1. The improved closet bowl herein described having a trap-seal whose passage or outlet is of uniform area throughout, a main supply-passage leading to the trap-seal on the opposite side thereof from its outlet or discharge, said main supply-passage being of uniform area in cross-section to the waterline of the trap-seal and gradually diminishing in area from said water-line to its communication with said seal, and having a hollow rim and a passage inclining upwardly from the main supply-passage to and opening into the said hollow rim substantially as set forth.

2. A closet-bowl having a trap-seal, a hollow rim, a main supply-passage leading downwardly to the trap-seal and gradually diminishing in area toward its lower end, and a passage leading upwardly from the main supply-passage to the hollow rim.

3. Acloset having a trap-seal, a hollow rim, a main supply-passage leading downwardly to the trap-seal and diminishing in cross-sectional area to its discharge to said seal and having a hollow rim and a passage leading upwardly from the main supply-passage to said hollow rim, substantially as set forth.

4. A closet-bowl having a trap-seal, a hollow rim, a main supply-passage leading downwardly to the trap-seal and an inclined passage relatively smaller than the main supplypassage communicating at its lower end directly with said main supply-passage at a point above the'delivery end of the latter and leading thence upwardly to the rim, substantially as set forth.

5. A closet-bowl having a trap-seal, a hollow rim, a main supply-passage leading downward on the back of bowl and communicating directly with the trap-seal opposite the seal outlet or discharge, said main supply-passage being of uniform area in cross-section to the water-line of the trap-seal and gradually diminishing in area from said water-line to its communication with said seal and said communication being directed downwardly into the trap-seal, and an inclined passage communicating directly with the main supplypassage and leading upward to the hollow rim substantially as set forth.

6. A closet-bowl having a trap-seal, a hollow rim, a main supply-passage leading clownward on the back of bowl and communicating directly with the trap-seal, opposite the seal outlet or discharge which said main supplypassage does not diminish in cross-sectional area to the water-line of said seal, and gradually diminishes in area from said water-line to its communication with said seal, said communication being directed downward into said seal, and an inclined passage relatively smaller than the main supply-passage, and having a direct, and unobstructed communication at its lower end with the main supply-passage, and leading upward to the hollow rim substantially as set forth.
